Cars Front Lights Idea
It would be helpful if the front lights of cars at night time would help other drivers to know if this car that is approaching from behind is moving fast or slowing down. Idea is that when the driver of the car that is approaching from behind hits breaks his front lights dim a little, if he/she pushes breaks harder the front lights dim more accordingly. Just as it happens with back break lights but vice versa - the harder push on breaks, the lighter back break lights and darker front lights. I guess there could be special front break lights for that purpose.
Maybe this idea is utopian but who knows maybe it worth thinking about. One thing for sure, something like this would help drivers at night to know if the car approaching from behind is seeing you slowing down (and slowing down too) or not.
